IMPROVED MODE OIE' LUBRICATING- JOURNALS.

The seneauie'refema' s in the 'Leners Patent and leaking pari of n., same.

To all to whom these presents 'shall come.-

Be it knownthat'I, SAMUEL NASH, ofBoston, in ,the county of Suiolk, and Commonwealth of Massachusetts, have made an invention of a new and use. fnl Mode of Lubricating Stationary Journals 4and do hereby declare the following-to be a full, clear, and exact description thereof, due reference being had to the accompanying drawings, making part of this specication, andin which- Figure l is a longitudinal, and

Figures 2 and 3, transverse sections of a carriagewheel, and axle-journal, and journal-box, showing the embodiment of my invention iu one example of adaptation.

' yThis invention is an improved mode of lubricating the' journals aud vboxes of the axles of wheeled vehicles, of connecting-rod bearings of steam and other engines, or loose pulleys, and, in fact, any stationary journal about which a body is in revolution, and relates to means whereby a greater quantity of lubricating-material may be introduced and held in reserve, without the necessity of replenishing, exceptat long intervals of time.

In the drawings before alluded to, land which are .hereto annexed, I have shown, asone 'iforrn of applying the principle of my invention, a carriage-wheel and axlejournal, such wheelbeing denoted by the letter a,the journal at b, and the journal-box at c, the nut ef such journal heilig seen at d, as screwed there` upon and against the end of the journal-box, in the usual manner. w

In pursuance-of my invention, I- bore, or otherwise form in the interior of the journal l), a longitudinal chamber or reservoir, e,such reservoir being preferably scored at both ends, in order to prevent leakage therefrom.

This reservoir, for obvious reasons of utility, should be of as large capacity as will be possible, consistent with safety, and may be of somewhat greater area, if

considered desirable, as it approaches the outer end of the journal.

An oritice, f, of atteuuatedwdth, but of considerable length, is cut through the journal and opening into the reservoir or well, e, this orifice, as well as a portion, or the whole of the reservoir, being packed with a suitable absorbent and attractive material, such as cotton, tow, ax, or other fibrous or porous substances.

This substance serves, bycapillary or other attraction, to absorb and convey the lubricating-'material from the reservoir to the movable surfacesin contact with the journal, and eiectually lubricate the parts in contact, the sizeof the reservoir being capable of containing such a large quantity of lubricating-material, in comparison to any device for the purpose heretofore devised, as to render the act'of refillingit necessary only at corresponding long intervals of time.

For convenience in replenishing the reservoir o, I bore a small hole, g, through the periphery ofthe outer end of the journal, and vleading into the ol` chamber e, a hole, h, of similar size, being alsorbored radially through' the nut d, -to coincide with and prolong the said hole g, when such nut Yis screwed up tn its place against the shoulder of the journal, or against the journal-boxe. v

The hole lt should be filled by a screw, i, such -screwserving not only as a removable plug, to allow 0f eri-j trance of oil to the oil-chamber, but as' a safety-stop against unscrewing and loss of the nut, which, in case of wheeled vehicles, not unfrequeutly occurs.

. The orifice f may -be multiplied to any extent found necessary. 1t is believed, however, that for the ma jority of journals, one will be found to possess a lib- Y eral oil-discharging area. `I am aware that it is not new to form a lubricatingchamber within an axle, and I make no claim to this; but

What I claim as my invention,and desire to secure by Letters Patent, is- I Y The combination, with the hollowjournal perforated at g, and the retaining-until, with its corresponding perforation h, of th piu or sfcrew i, whichris inserted in said perforation, and serves not only as a iplug to close the lubricatinglchamber, but also as a'stop to hold the nut in its proper position, as herein shown and set forth.
